Structure and function come unglued in the visual cortex.
In this issue of Neuron, Chowdhury and DeAngelis report that training monkeys to perform a fine depth discrimination abolishes the contribution of signals from area MT to the execution of a different, coarse depth discrimination. This result calls into question the principle of associating particular visual areas with particular visual functions, by showing that such associations are modifiable by experience.
